I started with fasciculations about 21 months ago. They were random and then noticeably more in my calves. Over the course of months, the twitching would come and go and be random. Stress would increase them sometimes, as would running. I had two EMGs done in 3 months time. Both were negative. I also was told that I have 2-3 beats of clonus. Reflexes are strong. I read this site and articles associated with it and felt better for a long time. However, i found myself worrying again. I came across more than a few people who started with BFS that later were diagnosed with A**. Is it true that clean EMGs, fascics, even clonus, can really be leading to a later diagnosis of A**??
